• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh ((thuong cua) OR (((truong cua) OR (truong cao)))) nhung cong ban thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh ((thuong cua) or (((truong cua) OR (truong cao)))) nhung cong ban thanh cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh ((thuong cua) or (((truong cua) OR (truong cao)))) nhung cong ban thanh cau*.
